VKBA 5416/804162 A Hub Bearing for Commmercial Vehicle JITO/OEM

Function

• Load bearing: As a wheel hub bearing, it needs to bear the radial load of the truck wheel (from the vehicle’s own weight, cargo weight, etc.) and the axial load (axial force generated by the driving force, braking force, etc. during the vehicle’s driving process) at the same time to ensure that the wheel can stably support the vehicle’s weight and rotate normally.
• Precise guidance: Provide precise guidance for the rotation of the wheel, ensure the accuracy and stability of the wheel during rotation, reduce vibration and noise, and make the vehicle drive more smoothly.

Application

• These two types of bearings are mainly used in the wheel hub of MAN trucks, suitable for related models such as Man Bridge, and are key components of the truck wheel end system, which has an important impact on the safe driving and performance of the vehicle.

Maintenance

• Regular inspection: Every time the vehicle is maintained, the condition of the wheel hub bearing must be checked, including checking the bearing clearance, abnormal wear, grease leakage, etc. A preliminary judgment can be made by listening to the sound, feeling the vibration, etc. If abnormal noise or vibration is found, further inspection and repair should be carried out in time.
• Lubrication maintenance: According to the recommendations of the vehicle manufacturer, the grease of the wheel hub bearing should be replaced regularly. Generally speaking, the wheel hub bearing needs to be replaced with grease every 20,000 to 30,000 kilometers or 2 to 3 months (whichever comes first). When replacing the grease, use the appropriate grease that meets the vehicle requirements, and clean the bearings and related parts to ensure that no impurities are mixed in.
• Installation and removal: When installing and removing the bearings, use professional tools and correct methods to avoid damage to the bearings. When installing, ensure that the bearings are installed in place and the installation accuracy meets the requirements. For example, the preload of the bearings should be adjusted to the appropriate value. Too tight or too loose will affect the service life and performance of the bearings.
• Cleaning and protection: Keep the wheel hub bearing clean to prevent dust, dirt and water from entering the bearing to avoid wear and corrosion. During the driving of the vehicle, if it passes through harsh road conditions or environments, the wheel hub should be cleaned and inspected in time.

We have completely production line, and are always strictly controlling each process of production, from raw material making, turning to heat treatment, from grinding to assembly, from cleaning, oiling to packing etc. The operation of each process is very meticulously. In the process of production, through self-inspection, follow inspection, sampling inspection, full inspection, such as strict as quality inspection, it made all the performances reached the international standard. At the same time, the company set up advanced testing center, introduced the most advanced testing instrument: three coordinates, length measuring instrument, spectrometer, profiler, roundness meter, vibration meter, hardness meter, metallographic analyzer, bearing fatigue life testing machine and other measuring instruments etc. About the quality of the product to entire prosecution, the comprehensive performance of comprehensive inspection products, ensure JITO to reach the level of zero defect products！
